Not quite related to kernel development per see, but I though,
nevertheless it would be of interest to many folks here.

I have been investigating a machine-independent change to GCC that would generate code to protect applications from stack-smashing attacks. The main characteristics are low performance overhead of the protection code, protecting against different varieties of stack-smashing attacks, and supporting various processors. A research report is ready on the web (http://www.trl.ibm.co.jp/projects/security/propolice).

I would like some feedback whether it is worth pursuing getting it assigned to the FSF for inclusion in GCC.
